Is sleeping a sport?

I used to play a lot of football (soccer).
Now I just walk for exercise.

Disc golf, it's barely a sport but I enjoy it.

I used to in elementary & high school.

i don't play sports anymore because i'm afraid i'll get so many injuries

also Football is the most dangerous sport ever

Basketball

Rodeo

Soccer

Squash

Is being a lazy piece of crap a sport?
